ATTO NEY Patented Oct. 29, 1935 UNITED STATES PATENT oFFIcE (Granted under the act of March 3, 1883, as amended April 30, 1928; 370 O. G. 157) 4 Claims.

This invention relates to a saw setter and has for an object the provision of an improved saw setter especially adapted for use on setting the teeth of a band saw.

A further object of this invention is to provide a saw setter that can be used to set the teeth of a band saw without the necessity of removing the band saw from its operative position.

A further object of this invention is to provide a saw setter which can be used to set the teeth of a band saw in a minimum amount of time.

A further object of this invention is to provide a saw setter which may be quickly and easily set into position on a band saw table, making use of the saw slot in the table to hold the same in operative position for setting teeth in the band saw passing through the slot.

A still further object of this invention is to provide a saw setter which, while especially useful for a band saw, is not limited in use to band saws but may be used in any type of saw.

A still further object of this invention is to provide a saw setter having a detachable and replaceable saw tooth setting wheel which may be replaced by a wheel having setting teeth of the proper size and set for the particular saw that is to be set.

A further object of this invention is to provide a saw setter having a yielding or cushioning means for adjustably holding the saw blade against the saw setting wheel. a

With the above and other objects in view the invention consists in the construction, combination and arrangement of parts as will be described more fully hereinafter.

Reference is to be had to the accompanying drawing forming a part of this specification in which like reference characters indicate corresponding parts throughout the several views, and in which:

Fig. 1 is an elevation side view of the saw setter in operative position;

Fig. 2 is a front view of Fig. 1;

Fig. 3 is a top view of Fig. 1;

Fig. 4 is a detailed view of the saw setting wheel;

Fig. 5 is a top plan view of Fig. 4; and

Fig. 6 is a section on line 66 of Fig. 4.

A There is shown at III the saw setter constituting this invention. Saw setter I0 includes a stand II, which is adapted to be mounted on the saw table I2 by means of securing plate I3 passing through the saw slot I4 and secured by means of the arm I5 and thumb screw I6 which is used to tighten the end of arm I5 against the bottom of the table, the arm I5 passing through the aperture H of the securing plate I3. The plate I3 is secured to the stand II by means of a machine screw I8 passing through the aperture I9. quickly and easily secured to the saw table I2 by passing the securing plate I3 through the saw slot I4 and then passing the arm I5 through the aperture I! in the plate I3, one end of the arm As will be obvious, the stand II may be :5 abutting against the bottom of the table and thereof, which receives a shaft 26 passing 15 through the stand II. A cover 2I complementary to the upper section of the stand II is secured thereto by means of stud bolts 22 passing through the projecting flanges 23 of the cover and 24 of the stand so as to hold the cover 2I sufficiently spaced from the stand II to permit the saw setting wheel 25 to rotate therein. The saw setting wheel 25 is provided with the key slot 26 so that it may be secured on the shaft 20 and rotatedxby means of the crank handle 21. Saw setting teeth 28 are provided with the proper size and pitch according to the size and pitch of the saw teeth 29 of the saw 36 that is to be set, it being observed that as illustrated the saw 30 is a band saw of the endless type that passes through the saw slot I4 of the table I2. The saw blade 30 is held with its teeth 29 against the teeth 28 of the saw setting wheel 25 by means of a clamp 3| which is slotted to permit the saw blade 30 to pass therethrough. The clamp 3| is mounted on the threaded ends of four clamp rods 32, each clamp rod 32 being slidably supported in apertured bosses 33. The ends of the four clamp rods 32 are secured together by a U-shaped clamp pin 34 and by a end as of thumb bolt 31 to pass freely through 5 without contact. A rubber cushion 39 suitably apertured to permit the threaded ends 38 of the bolt 31 to pass freely therethrough is secured between the clamp guide plates 35 and 36. As will be apparent, tightening the thumb bolt 31 will u cause the threaded end 38 to abut against the rear of stand II and cover 2|, causing the plate 36 to press the rubber cushion 39 against the guide plate 35 and thus draw the clamp rods 32 and press the clamp 3| so as to hold the band saw 30 in proper position against the teeth of the saw setting wheel 25. Rotation of the crank handle 21 will then cause the wheel 25 to rotate, drawing the band saw 30 through the slot 3| and bringing its teeth 29 into contact with the teeth of the saw wheel 25, causing the teeth 29.

to acquire the same set and pitch as in the teeth 28 of the saw wheel 25.

When setting a saw having different pitch 'or set of teeth, it is only necessary to remove the cover 2|, take off the saw wheel 25, substitute another saw wheel having the appropriate set and pitch, and replace the same, enabling any desired set and pitch of teeth on any saw to: be properly adjusted. i

While the invention hasbeen described as particularly applicable for a band saw and the securing plate I3 is such that it makes use of the saw slot in the table, it is obvious that this saw setter may be used for any type of saw. It will be observed further that the saw setting wheel 25 when in operative position is in the same plane as the securing plate l3, and inasmuch as the securing plate I3 is in theplane of the saw slot in the table, then the saw setting wheel 25 is likewise in the plane of the band saw 30, thus properly aligning the band saw 30 and the wheel of the device by the mere operation of securing the saw setter in position.

It will be understood that the above description and accompanying drawing comprehend only the general and preferred embodiment of this invention, and that various changes in construction, proportion and arrangement of parts may be made within the scope of the appended claims, and without sacrificing any of the advantages of this invention.

The herein described invention may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment of any royalties thereon or therefor.
